Hooker now conceived a plan seductive by its audacity and its possible results. He proposed by a sudden movement to capture Richmond, presumably garrisoned very scantily, and to get back before Lee could make any serious impression at the North. It might have been done, and, if done, it would more than offset all the dreary past; yet the risk was great, and Mr. Lincoln could not sanction it. He wrote: "I think Lee's army, and not Richmond, is your sure objective point. If he comes towards the Upper Potomac, follow on his flank and on his inside track, shortening your lines while he lengthens his; fight him, too, when opportunity offers. If he stays where he is, fret him, and fret him."

This was good strategy and was adopted for the campaign. Ewell's corps crossed the Upper Potomac, and on June 22 was in Pennsylvania. The

corps of Longstreet and Hill quickly followed, and Lee's triumphant army, at least 70,000 strong, marched through the Cumberland Valley to Chambersburg and Carlisle, gathering rich booty of herds and grain as they went, with Harrisburg as an immediate objective, Philadelphia in no remote distance, Baltimore and Washington in a painfully distinct background. The farmers of western Pennsylvania, startled by the spectacle of gray-coated cavalry riding northward towards their state capital, cumbered the roads with their wagons. The President called from the nearest States 120,000 militia. General Hooker, released from his waiting attitude by the development of his adversary's plan, manoeuvred well. He crossed the Potomac at Edwards' Ferry, June 25-26, and drew his forces together at Frederick. It was then decided to move northward and to keep Lee as well to the westward as possible, thereby reserving, for the bearing of future events, the questions of cutting the Confederate communications or bringing on a battle.

An unfortunate element in these critical days was that Halleck and Hooker disliked each other, and that their ideas often clashed. Mr. Lincoln was at last obliged to say to Hooker: "To remove all misunderstanding, I now place you in the strict military relation to General Halleck of a commander of one of the armies to the general-in-chief of all the armies. I have not intended differently; but as it seems to be differently understood,

I shall direct him to give you orders, and you to obey them." At the same time he wrote him a "private" letter, endeavoring to allay the ill-feeling. He closed it with words of kindness, of modesty, and with one of his noble appeals for subjection of personal irritation and for union of effort on behalf of the country:—

"I believe you are aware that, since you took command of the army, I have not believed you had any chance to effect anything till now. As it looks to me, Lee's now returning towards Harper's Ferry gives you back the chance that I thought McClellan lost last fall. Quite possibly I was wrong both then and now; but, in the great responsibility resting upon me, I cannot be entirely silent. Now, all I ask is that you will be in such mood that we can get into our action the best cordial judgment of yourself and General Halleck, with my poor mite added, if, indeed, he and you shall think it entitled to any consideration at all."

The breach, however, could not be closed. Hooker, finding his army seriously weakened by the withdrawal of the two years' and the nine months' troops, asked for the garrison of Harper's Ferry, which seemed useless where it was. Halleck refused it, and, June 27, Hooker requested to be relieved of the command. His request was instantly granted, and Major-General George G. Meade was appointed in his place. Swinton says that command was given to Meade "without any lets or hindrances, the President expressly waiving

all the powers of the executive and the Constitution, so as to enable General Meade to make, untrammeled, the best dispositions for the emergency." One would like to know the authority upon which so extraordinary a statement is based; probably it is a great exaggeration, and the simple fact would prove to be that, since the situation was such that new developments were likely to occur with much suddenness, the President wisely and even necessarily placed the general in full control, free from requirements of communication and consultation. But to represent that Mr. Lincoln abdicated his constitutional functions is absurd! Be this as it may, the fact is that the appointment brought no change of plan. For three days the armies manoeuvred and drew slowly together. Finally it was betwixt chance and choice that the place and hour of concussion were determined. The place was the village of Gettysburg, and the time was the morning of July 1.

Then ensued a famous and most bloody fight! During three long, hot days of midsummer those two great armies struggled in a desperate grapple, and with not unequal valor, the Confederates fiercely assailing, the Federals stubbornly holding, those historic ridges, and both alike, whether attacking or defending, whether gaining or losing ground, always falling in an awful carnage of dead and wounded. It was the most determined fighting that had yet taken place at the East, and the names of Cemetery Ridge, Little Round Top, and

Culp's Hill are written deep in blood in American memories. When the last magnificent charge of the Southerners was hurled back in the afternoon of July 3, the victory was decided. The next day Lee began to send away his trains, his wounded and prisoners. It is indeed true that during the day he held his army in position on Seminary Ridge, hoping that Meade would attack, and that, with an exchange of their relative parts of assailants and defenders, a change of result also might come about. But Meade made no advance, and with the first hours of darkness on the evening of July 4 the Southern host began its retreat.
